The Impact

Oligopoly can be defined as a market model of the imperfect competition type, assuming the existence of only a few companies in a sector or industry, from which at least some have a significant market share and can therefore influence the production prices in the market. Many models of oligopoly that differ from one another mostly in the nature of the competitive companies’ behaviour can be found through the study of oligopolistic structures. Some models describe only the behaviour of two companies in the monitored market (duopoly), others describe several companies of the same power (cartel), still others assume that one of the companies has a dominant position in the market, etc. The text of this article deals with oligopolistic competition in the food market in the terms of the behaviour of grocers and with the impact of this competition upon the market competition in the sector. First, it mentions the agreements on common cooperation and procedure, when cartel market structure originates. It also analyzes the examples of behaviour of oligopoly with a dominant firm on the market with products in the food sector, with the goal of detecting whether the market with these products is significantly influenced by the oligopolistic behaviour of companies.

AbstractThe Coffee Berry Borer (CBB) is the main pest that affects coffee crops around the world, causing major economic losses and diminishing beverage quality. A mathematical model is formulated, from the perspective of the Adaptive Dynamics (AD) framework, to describe the evolution of coffee quality as a continuous differentiating attribute related to the mix of healthy and bored coffee. The study involves three stages: first, an agro-ecological model describes coffee production and growth of the CBB population prior to the processing of different qualities of coffee; second, a market model describes the competition between different blends of standard and special coffee; finally, the AD canonical equation is derived to describe the evolution of coffee quality resulting from innovations in the quality attribute filtered by market competition. Interestingly, AD allows to derive conditions for the emergence of diversity, i.e., the establishment of a second type of coffee that coexists with the former and, similarly, for subsequent branching in the quality attributes. The full model provides insights on the impact of CBB control strategies on the long-term market structure. Specifically, a strong control aimed at increasing coffee quality may impoverish the market diversity, independently of the consumers’ budget limitations and corresponding preference for either high or low quality.

The Impact

The integration processes in the modern world, caused by the dynamic globalization, which covers all sectors of the world economies, including the agri-food sector, which provides the world's population with food, are considered. The peculiarities of unification of national agri-food markets into a single world market and adaptation of domestic state policy of agricultural regulation in accordance with the principles defined by the World Trade Organization and the general direction of the common agricultural policy of the European Union are described. The peculiarity of the agri-food sector of Ukraine, which consists in the degree of development of domestic agriculture and ways of implementing the regulatory policy of the state in this area, is described. A study of the integration processes of the Ukrainian agri-food market and the imperfection of mechanisms for regulating the activities of agri-food enterprises by the state, which necessitates the adaptation of integration processes to international requirements. The advantages and disadvantages of enterprises entering the international market after Ukraine's accession to the World Trade Organization are considered. The impact of the biodiversity strategy until 2030, adopted by the European Commission, on the activities of domestic agri-food enterprises, the competitiveness of their products on the international market and stimulating the production of environmentally friendly products has been studied. The main Ukrainian exporters of agricultural products on the European agricultural market and the rating of the main demanded goods are studied. It is analyzed that the agri-food market of Ukraine functions in the conditions of strengthening of internal and external integration processes. The internal integration processes characterized by the vertical integration of Ukrainian agri-food enterprises, which contributes to the significant development of the agri-food sector, are considered. It is proved that the private form of land ownership is dominant in this market, the monopoly position is occupied by domestic agricultural holdings, which intensifies imperfect competition in the market.

Distribution Of Income

To realize economic and social sustainability, it is necessary to avoid economic injustice and therefore too unequal a distribution of income and wealth. In this paper we investigate the extent to which oligopolies contribute to an unequal income distribution, and the consequences of enforcing more market competition. For this purpose, an overlapping generation growth model is developed with imperfect competition to derive the influence of market concentration on economic growth and the distribution of income. We investigate the influence of market concentration on the inter- and intra-generational distribution of income and economic growth. We show that political lobbying and corruption are important reasons for missing competition in markets. While an increasing market concentration leads to a more unequal intra-generational distribution and to a redistribution of income from the old to the young generation, the impact on economic growth is in general ambiguous, and specifically depends on the cost of lobbying.

The Impact

The objective of this paper is to enhance the dominant research perspective of innovations in the food market (power or supply chain centric) with an interactive/network approach. Many scholars identify the development challenges facing the food sector, including economic factors, changes in lifestyle, climate change, changes to the food consumption mix, shrinkage of Earth’s resources and interactions between food production and the environment, in the context of sustainable development. A new approach to innovations in the food market may shift it towards a more sustainable path of development. Based on a literature review, we present the specific conditions for innovation in the food market and discuss previous research as being focused on the power of operators and flows in supply chains. Methodologically, this paper puts these considerations in the context of interaction and business networks. We note that the concept of power and dependence can be embedded with the concept of interdependence, and flows in supply chains can be replaced by the concept of cooperation in business networks. We conceptualize a research framework based on innovative activities in business relationships and networks and we propose the following themes as research avenues for further research: (1) What drives innovation in food ecosystems? (2) When is the power-centric approach to innovations more effective than taking the perspective of interdependence? (3) How do network-born innovations develop in the food sector? (4) How do actors handle innovation in their business models? (5) What is the impact of innovations on the food sector?

Using the case of Vietnam, this paper proposes an industrial organisation model of the food distribution system in developing countries. Since most work in this field has adopted an empirical approach, this paper will instead focus on a theoretical model based on the theory of imperfect competition applied in agricultural economics. We introduce two distribution channels of product differentiation linked vertically by demand, and study the quantity flow from small producers to consumers by means of a Nash equilibrium. We show that there is a Nash equilibrium of the food distribution system and market power, with effects on both farmers and consumers. The paper discusses the implications of these results and proposes policies to intervene in the market and mitigate its power to improve the wealth of both farmers and consumers. The competitive market model of the food distribution system presented in this paper is also important in analysing the policy implications of a food market with imperfect competition in developing countries.

The Impact

AbstractInforming and engaging citizens to adopt sustainable diets is a key strategy for reducing global environmental impacts of the agricultural and food sectors. In this respect, the first requisite to support citizens and actors of the food sector is to provide them a publicly available, reliable and ready to use synthesis of environmental pressures associated to food commodities. Here we introduce the SU-EATABLE LIFE database, a multilevel database of carbon (CF) and water (WF) footprint values of food commodities, based on a standardized methodology to extract information and assign optimal footprint values and uncertainties to food items, starting from peer-reviewed articles and grey literature. The database and its innovative methodological framework for uncertainty treatment and data quality assurance provides a solid basis for evaluating the impact of dietary shifts on global environmental policies, including climate mitigation through greenhouse gas emission reductions. The database ensures repeatability and further expansion, providing a reliable science-based tool for managers and researcher in the food sector.

The Impact

The aim of this paper is to assess the impact of reforms introduced in the operation of Polish open pension funds on management style, risk exposure and related investment performance. The article analyzes the impact of the reformed regulations on the herd behavior of fund managers. In particular, we examined whether the elimination of the internal benchmark for fund evaluation impacts the elimination or reduction of herd behavior. We proposed a multi-factor market model to evaluate the performance of funds investing in various types of instruments. Moreover, we used panel estimation to directly take into account the impact of the internal benchmark on herd behavior. Our results indicate that highly regulated funds may slightly outperform passive benchmarks and their unregulated competitors. In the case of Polish open pension funds, limiting investments in Treasury debt instruments clearly resulted in increased risk and volatility of returns. However, it also raised competition between funds and decreased the herd behavior. Additionally, the withdrawal of the mechanism evaluating funds based on the internal benchmark was also important in reducing herd behavior.
